Building a Wireless Kill Switch
When things become sentient, it's good to be able to remotely kill power.
I highly recommend building something that scares you every once and a while. In this case, I’m planning to enter an autonomous vehicle into the AVC in 2016, and it's pushing my limits of comfort. A 1,000W motor with a large battery pack behind it means that if things go wrong, they go really wrong!
The innards of the remote kill switch
For that reason, one of the new safety requirements of the AVC rules is a remote kill switch that allows the user to safely and remotely power down the vehicle. So here's a tutorial going into how I built the wireless kill switch based on the RFM69. And to demonstrate this... well... let's start with a margarita.

Learn how to build a wireless controller to kill power when things go... sentient.
But what does the WHITE button do?!
It shoots flowers out one end of the remote.
Glad Nate is back at engineering. He is one of my favorite faces to see at Sparkfun!
Thanks! Trying to carve out more time to do fun projects.
Me too
Add an alcohol sensor to the remote and you could control the blender based on what BAC you blow.
So at 1:36 when you you were talking about the remote going too far away, for a moment I expected you to toss it off the roof.
Hah! I should have. Next time...
I got the same impression!
That makes three of us!
